Sometimes, the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. How could you improve your experiment?

A. Hydrolyze the hormone before application. B. Add ATP as a cofactor. C. Apply the hormone to mouse cell culture. D. Apply the hormone at a concentration of 0.5 M.
